Converting residential air conditioning equipment that uses R-22 to a replacement refrigerant is seen by many contractors and homeowners as a good way to extend the life of the system while removing R-22 from the picture. There are a number of replacement refrigerants to choose from, but with any replacement, it’s important to remember that the refrigerant is only half of the equation.
Sales of cooling equipment increased this summer, according to the Air-Conditioning, Heating, and Refrigeration Institute (AHRI), whose combined June and July 2017 reports showed that U.S. shipments of central air conditioners and air-source heat pumps were up about 5.7 percent compared to units shipped during the same time frame in 2016.
Midea has won the bid to provide central air conditioning systems for seven stadiums in Russia. Midea will offer comprehensive air conditioning solutions for the stadiums with its leading falling film water-cooled screw chillers, MAi full inverter intelligent variable refrigerant flow (VRF) systems, and fan coil units.
Visitors to the Ernest Hemingway Home and Museum in Key West, Florida, enjoy stepping back in time to see how the prolific author lived during his 10 years in residence there in the 1930s. The two-story home was built in 1851 in the Spanish Colonial style, constructed of native limestone hewn from the grounds. The home was in poor shape when Hemingway and his wife, Pauline, purchased it, but the couple could see beyond the rubble and ruin to appreciate the grand architecture and stateliness of the home.
This panelized jacket design for Westinghouse’s F-Series air conditioners and heat pumps features removable panels instead of a one-piece jacket for easier service.
Subcooling can be a somewhat difficult topic for new technicians starting out in the industry. In fact, few topics garner as many questions from green techs than subcooling does.
The ICExp “EXNA” family of air conditioners is certified for use in hazardous locations. These wall-mounted products cover 28 models from 12,000- to 72,000-Btuh self-contained packages in single and three-phase voltage for operation on 60- and 50-Hertz power supplies.
Energy efficiency ratings (SEER/EER) of air conditioners and heat pumps keep rising, thanks to new technologies such as electronically commutated motors (ECMs), inverter-driven compressors, and advanced heat exchangers. These technologies have helped boost high-end cooling equipment ratings to the mid-20-SEER range, which was unthinkable just a few years ago.
The condensing unit market is on the rise. According to a report published by MarketsandMarkets, the global condensing unit market is forecast to reach $23.31 billion by 2021, growing at a compound annual growth rate (CAGR) of 11.1 percent from 2016 to 2021. And there are a number of trends contributing to this growth.
